System for connecting flat structural elements

Abstract

The present invention relates to a new connection system that facilitates the reversible, quick and secure joining of planks or other constructive materials with a flat surface. The connection system is based on the fact that one of the pieces to be joined has a set of hooks or male connectors arranged in a linear series, the separation of which coincides with that displayed by a set of die cuts or female connectors arranged in a series on the second piece to be joined. The die cuts or female connectors are characterised in that they are bottle shaped. The hooks or male connectors may only be inserted in the punches or female connectors by means of sliding. The connection system may have one or more linear series of hooks or die cuts. The connection system makes it possible to join structural elements, such as planks, boards or panels, be it to one another or by means of a free connector, which adjusts and assembles them. In the first case, the structural elements may have the series of male or female connectors die cut or might have pieces stuck or joined to the same, upon which said punches are arranged. In the second case, one or various structural panels may have a connector, whether male or female and the free connector have the corresponding male or female connector. This free connector element facilitates the joining of a panel or various panels by means of sliding. The connection system facilitates rapid, reversible construction, without tools, of structures as diverse as temporary stands, packaging, the boxing industry and wooden or concrete constructions.

1 . A constructive system for constructing stands and display cases and compartmentalising offices that facilitates the joining of flat pieces or structural elements characterised in that two or more pieces have one or more linear series of hook shaped protuberances and the remaining pieces have one or more series of bottle shaped cuts, the fixing mechanism of which consists in the reversible insertion and sliding of a piece with bottle shaped cuts into two or more panels provided with one or more linear series of hook shaped protuberances, said hook shaped protuberances coinciding, in such a way that a hook shape is adopted. 
     
     
         2 . The constructive system according to  claim 1 , characterised in that the hook shaped protuberances or male connections are located on the margin of the flat pieces or structural elements. 
     
     
         3 . The constructive system according to  claim 1 , characterised in that the hook shaped protuberances or male connections are located on any non-marginal area of the flat pieces or structural elements. 
     
     
         4 . The constructive system according to  claim 1 , characterised in that the hook shaped protuberances or male connections were originated in the flat pieces or structural elements or the series of hooks were subsequently joined to the same. 
     
     
         5 . The constructive system according to  claim 1 , characterised in that the hook shaped protuberances or male connections are arranged in such a way that they are not equidistant. 
     
     
         6 . The constructive system according to  claim 1 , characterised in that the hook shaped protuberances or male connections are made in different sizes. 
     
     
         7 . The constructive system according to  claim 1 , characterised in that the hook shaped protuberances or male connections have been made in different shapes. 
     
     
         8 . The constructive system according to  claim 1 , characterised in that the series of bottle shaped cuts or female connections are die cut in any non-marginal area of the flat pieces or structural elements. 
     
     
         9 . The constructive system according to  claim 1 , characterised in that the element inserted by means of sliding consists of a free, non-structural piece or free connector element, which joins two or more flat pieces or structural elements. 
     
     
         10 . The constructive system according to  claim 9 , characterised in that the free connector element has male protuberances and female cuts at the same time, which enables it to serve as a closure and hook. 
     
     
         11 . The constructive system according to  claim 9 , characterised in that the free connector element has an expansion, which serves as a brace. 
     
     
         12 . The constructive system according to  claim 1 , wherein the flat pieces or structural elements comprise both flexible materials, including plastics, papers, cards and foams and rigid materials, including corrugated cardboard, rigid cardboard, honeycomb cardboard, polypropylenes, vinyl, acrylics, aluminium, compound resins, rubbers, rigid foams and wood. 
     
     
         13 . The constructive system according to  claim 1 , wherein the flat pieces or structural elements comprise cellulose, plastic, stone-like, glass and cement materials. 
     
     
         14 . The constructive system according to  claim 13 , characterised in that the flat pieces or structural elements comprise ecological materials or materials made from recycled materials. 
     
     
         15 . The constructive system according to  claim 4 , wherein there is a bevelled cut adjacent to the hooks when they are originated in the flat pieces, such that makes it possible to fold the series of hooks until they adopt a position perpendicular to the original position.
